Question

Strategic placement of lobster traps is one of the keys for a successful lobster fisherman. A study was conducted of the average distance separating traps called trap spacing deployed by lobster fishermen. The​ trap-spacing measurements​ (in meters) for a sample of seven teams from fishing cooperative​ A, and a sample of eight teams from fishing cooperative B are repeated in the accompanying table. For this​ problem, we are interested in comparing the mean​ trap-spacing measurements of the two fishing cooperatives.​ (Since the sample from fishing cooperative A is listed​ first, treat it as the first​ sample.)

A​ Cooperative: 102
